I am currently working on "SuccessFactors HCM Suite Onboarding with SAP ERP HCM" via HCI as Middleware for the first time. I could not find any documentation related to Onboarding. Could you please guide me how to Configure the process one by one.

I am using the below interfaces:

1) Begin Session (Sender side & Receiver Side URL's)

2)Cancel Session (Sender side & Receiver Side URL's)

3)GetNewHireRecord (Sender side & Receiver Side URL's)

4)Onboarding Candidate Info (Sender side & Receiver Side URL's)

Please let me know what is the process to trigger and from where we have to trigger the Interface.
